Feasibility of a Telephone Intervention for HIV Patients and Their Informal Caregivers

Objectives: To assess the feasibility of a telephone intervention for HIV-positive patients and their caregivers. Methods: HIV-positive participants, some co-enrolled with their informal caregiver, enrolled in this randomized study. Intervention-arm participants (124 patients and 76 caregivers; dyads assigned to same arm) received up to 12 scheduled calls from an interventionist over 6 months. Results: An average of 7.6 (SD = 3.0) calls to each participant was completed; 66.5% received at least 6 calls; 43.0% received more than 75% of the intervention (defined as ‘study adherent’). Having a higher T-cell count was associated with call adherence (p = .014); cocaine use was associated with reduced call adherence for both patients (p = .019) and caregivers (p = .083). Common telephone themes included problems with mood, relationships, finances, housing, and work; interventions (e.g., referral for mental health care) were initiated in response to these. Participant satisfaction was high, and many reported benefits from the intervention. Conclusions: Using a telephone intervention with HIV-positive patients and their caregivers is a feasible and potentially beneficial intervention.

Observers’ reactions to workplace incivility in the masculine domain: How does role congruency explain gender bias in future workers?

Based on Role Congruity Theory, we tested the hypothesis of gender bias by examining gender differences in observers’ evaluations of the awareness and acceptability of workplace incivility gender‐dyad interaction. Three hundred and ninety‐six Spanish high school students (55.3% female) read one scenario of overt incivility (publicly humiliates and openly doubts the employee's judgment) or covert (omits and pays little attention) from a leader (female vs. male) toward a subordinate (female vs. male) in engineering. Results indicated gender differences among observers. From the leader actor of incivility, males were more aware and accepted less the incivility when performed by a female leader in a male domain; whereas females were more aware and accepted less incivility than males in all cases. Regarding the subordinate target of incivility, only females were more aware and accepted less incivility, and both males and females were more aware and accepted less covert incivility. Our results reveal practical implications for interventions from a gender perspective.     

Finger inter-dependence: linking the kinetic and kinematic variables

We studied the dependence between voluntary motion of a finger and pressing forces produced by the tips of other fingers of the hand. Participants moved one of the fingers (task finger) of the right hand trying to follow a cyclic, ramp-like flexion-extension template at different frequencies. The other fingers (slave fingers) were restricted from moving; their flexion forces were recorded and analyzed. Index finger motion caused the smallest force production by the slave fingers. Larger forces were produced by the neighbors of the task finger; these forces showed strong modulation over the range of motion of the task finger. The enslaved forces were higher during the flexion phase of the movement cycle as compared to the extension phase. The index of enslaving expressed in N/rad was higher when the task finger moved through the more flexed postures. The dependence of enslaving on both range and direction of task finger motion poses problems for methods of analysis of finger coordination based on an assumption of universal matrices of finger interdependence.     

Differential sensitivity of recent vs. remote memory traces to extinction in a water-maze task in rats

Extinction has mostly been studied in conditioning paradigms, more sparsely in spatial tasks, and never as a function of the age of a spatial memory. Using rats, we compared the time-course of extinction of a recent (5 days) vs. remote (25 days) spatial memory in a water maze, over three probe trials. When the trials were set 24h apart, performance in the remote memory group was significantly worse on the first probe trial and significantly better on the third probe trial, as compared to the recent memory group, thereby showing differences between cognitive operations underlying recent vs. remote memory extinction. In contrast, when trials were given consecutively, both groups showed a similar profile of extinction. Furthermore, in a room with overly-salient cues providing a strong remote memory trace, no difference between groups was observed when the spaced extinction paradigm was used. These results might be related to a balance between reconsolidation and extinction processes occurring after a first retrieval experience, of which the outcome may depend on the extinction protocol, and on the age and strength of a memory.     

Effects of auditory input in individuation tasks

Under many conditions auditory input interferes with visual processing, especially early in development. These interference effects are often more pronounced when the auditory input is unfamiliar than when the auditory input is familiar (e.g. human speech, pre‐familiarized sounds, etc.). The current study extends this research by examining how auditory input affects 8‐ and 14‐month‐olds’ performance on individuation tasks. The results of the current study indicate that both unfamiliar sounds and words interfered with infants’ performance on an individuation task, with cross‐modal interference effects being numerically stronger for unfamiliar sounds. The effects of auditory input on a variety of lexical tasks are discussed.     

When we feel good and bad about ourselves: self-esteem memories across cultures

Young adults in the United States, Croatia, and China described personal episodes of times when they felt especially good or bad about themselves. These self-esteem memories were either recent (episodes that occurred during the previous 4 weeks) or remote (episodes that occurred between the ages of 10 and 15). Systematic content differences between memories of positive and negative self-worth were apparent primarily for remote rather than for recent memories. Across cultures, long-lasting positive memories frequently represented achievement themes, whereas negative memories frequently represented social themes. Links between achievement success and positive self-regard, and between social distress and negative self-regard, are explained using theories of self-esteem and autobiographical memory.
